…ing variants - provider.ts: override models.dev incorrect context/output limits for GitHub Copilot Claude models in fromModelsDevModel(). models.dev reports wrong values (e.g. claude-opus-4.6 as 144k context) vs Anthropic docs. - transform.ts: fix @ai-sdk/github-copilot claude branch in variants() to return adaptive effort levels (low/medium/high/max for opus-4.6 and sonnet-4.6; high/max for other claude models) instead of a single hardcoded 'thinking' variant. Fixes anomalyco#20317

Type of change
What does this PR do?
Two bugs affect Claude models when used via the GitHub Copilot provider:
1. Wrong context/output limits —
models.devhas incorrect values for GitHub Copilot Claude models (e.g.claude-opus-4.6is listed as 144k context/64k output, correct is 1M/128k). Fixed inprovider.tsinsidefromModelsDevModel()with a lookup table that overrides the wrong values for Copilot+Claude combos, using the values from Anthropic's official model documentation.2. Missing adaptive thinking variants —
transform.tshad a@ai-sdk/github-copilotbranch that returned only a single hardcodedthinkingentry for any Claude model. TheisAnthropicAdaptivevariable (already computed at the top ofvariants()) was unused in this branch. Fixed to returnlow/medium/high/maxfor adaptive models (opus-4.6,sonnet-4.6) andhigh/maxfor other Claude models, matching the Anthropic direct-provider behavior.How did you verify your code works?
models.devAPI and confirmed the wrong values are presentvariants()function and confirmedisAnthropicAdaptivewas already correctly detecting the model IDs but was never used in the@ai-sdk/github-copilotbranchChecklist
